Sonar Control Unit cabling

All the cables to the Sonar Control Unit are to be plug connected

to the electronic drawer unit at the rear of the cabinet (see figure

13). The numbers on the figure refer to the cable numbers on the

cable plan.

Note In order t o make service on the Sonar Control Unit, the cables

must have a slack so the electronic drawer unit can have all the

cables connected while it is outside the cabinet. This could be

either by pulling it out from the front, or by reconnecting t he

cables with the drawer at floor level.
